It's more likely than you think!
For those of you who aren't cosmologists, here's the TL;DR:
They found some bacteria fossils encased in a meteorite. These organisms are (much like?) cyanobacteria, which don't grow when they are dry, they just shut up and exist. However, these fossils had grown. The catch is that the meteorite would have dissolved if it were exposed to water.
So these bacteria would have had to grow in water, then be encased in the rock and be ejected into space somehow. IS IT EXTRATERRESTRIAL LIFE?
Signs point to yes, since shooting something into space from Earth would melt/vaporize it.
Here, maybe Reddit can explain it better.
So while the real scientists debate this paper, let's make wild, uninformed guesses. Could this rock have come from Earth, and if not, why and how much should we care?
